Abstract
Description
Die Erfindung betrifft eine Tragplatte für ein Gebißmodell.The invention relates to a support plate for a denture model.
Zur Anfertigung von Zahnersatz, z.B. Zahnkronen, Brücken, Inlays etc. wird vom
Zahntechniker ein positives Gebißmodell des Patienten benötigt.
Dabei werden die vom Zahnarzt gelieferten negativen Abformungen des Ober- und
des Unterkiefers des Gebisses eines Patienten mit einer Modellmasse, z.B. Gips,
ausgefüllt und jeweils eine Tragplatte angedrückt, die mit Haltestiften bestückt ist,
die in die Modellmasse hineinragen und nach dem Aushärten der Modellmasse in
der Modellmasse steckenbleiben.
Nach Aushärtung der Modellmasse ist nach Entfernen der negativen Abformung ein
postives Gebißmodell des Ober- oder Unterkiefer des Patienten auf einer Tragplatte
entstanden.The dental technician needs a positive denture model of the patient to manufacture dentures, such as tooth crowns, bridges, inlays, etc.
The negative impressions of the upper and lower jaw of a patient's dentition supplied by the dentist are filled with a model mass, e.g. plaster, and a support plate is pressed on, which is equipped with retaining pins that protrude into the model mass and after the model mass has hardened in of the model mass.
After the model mass had hardened, a positive denture model of the patient's upper or lower jaw was created on a support plate after removing the negative impression.
Dieses positive Gebißmodell mitsamt der Tragplatte wird mit einem entsprechenden
positiven Gegenkiefermodell des Patienten in einem Gebißbewegungssimulator
(Artikulator) montiert, wodurch individuelle Gebißbewegungen des Patienten nachgeahmt
werden können.
Dadurch ist eine auf die Gebißstellung und -bewegung des Patienten abgestimmte,
paßgenaue Anfertigung von Zahnersatz möglich.This positive dentition model together with the support plate is assembled with a corresponding positive opposing jaw model of the patient in a denture movement simulator (articulator), whereby individual patient dentition movements can be imitated.
This makes it possible to produce dentures that are tailored to the patient's dentition position and movement.
Das auf der Tragplatte aufsitzende Gebißmodell muß zur Bearbeitung von der
Tragplatte entfernt und wieder auf diese zurückgesetzt werden.
Häufig muß das Gebißmodell zudem in Kiefer- oder Zahnsegmente zersägt werden,
um das Arbeiten an diesem Segment zu erleichtern.
Dabei wird zunächst das Gebißmodell mitsamt der Haltestifte von der Tragplatte
abgehoben und anschließend in einzelne Segmente zersägt.
Danach werden die einzelnen Gebißmodellsegmente mittels der Haltestifte wieder
möglichst genau an ihre frühere Position auf der Tragplatte zurückgesetzt und verbleiben
so fest an der Tragplatte, auch bei einer oberseitigen Montage der Tragplatte
in einen Artikulator, bei dem die Zahnreihe des Gebißmodells nach unten
gerichtet ist. The bit model sitting on the support plate must be removed from the support plate for processing and put back on it.
Often, the denture model also has to be sawn into jaw or tooth segments to make working on this segment easier.
First, the denture model together with the retaining pins is lifted off the support plate and then sawn into individual segments.
Then the individual denture model segments are reset as accurately as possible to their previous position on the support plate by means of the retaining pins and thus remain firmly on the support plate, even when the support plate is mounted on the top in an articulator, in which the teeth row of the denture model is directed downward.
Es ist eine Tragplatte für ein Gebißmodell aus der PCT-Patentschrift WO 98/10709 bekannt, die auf ihrer Oberseite mit einer bogenförmigen Vertiefung versehen ist, deren Seitenwände senkrechte Rillen aufweisen und in deren Boden zahlreiche Bohrungen mit eingesteckten Haltestiften vorgesehen sind.It is a carrier plate for a denture model from PCT patent WO 98/10709 known, which is provided on its top with an arcuate depression, the side walls have vertical grooves and numerous in the bottom Holes with inserted retaining pins are provided.
Die Haltestifte bestehen aus Kunststoff und werden beim Zersägen des Gebißmodells in einzelne Kiefer- oder Zahnsegment gegebenfalls mit zersägt, was die Sägearbeit stark behindert und angesägte Haltestifte übrig läßt.The holding pins are made of plastic and are used when sawing the denture model sawed into individual jaw or tooth segments if necessary, which is the sawing work severely handicapped and left sawed retaining pins.
Desweiteren nachteilig ist bei der bekannten Tragplatte, daß alle in die Bohrungen am Boden der Vertiefung auf der Tragplatte eingesteckten Haltestifte im ausgehärteten Gebißmodell steckenbleiben und nicht entfernt werden können, was das Abnehmen und das Zurücksetzen des Gebißmodells bzw. einzelner Gebißmodellsegmente von der Tragplatte oder auf die Tragplatte erheblich erschwert und zu einem Abrieb oder Bruch der Modellmasse durch ein Verkanten der Haltestifte in den Bohrungen und ein schräges Abheben oder Aufsetzen des Gebißmodels oder einzelner Segmente auf die Tragplatte führt.Another disadvantage of the known support plate that all in the holes at the bottom of the recess on the support plate inserted in the hardened Denture model get stuck and cannot be removed, what the weight loss and resetting the bit model or individual bit model segments from the support plate or onto the support plate considerably more difficult and to one Abrasion or breakage of the model mass due to tilting of the retaining pins in the Drilling and an oblique lifting or putting on the bit model or individual Leads segments on the support plate.
Nach dem Aushärten der in die negative Abformung des Gebisses eines Patienten gefüllten flüssigen Modellmasse, z.B. Gips, auf die die Tragplatte der bekannten Bauform vor der Aushärtung aufgesetzt wurde, weist das aus der Vertiefung der Tragplatte gehobene positive Gebißmodell an den Außenwänden eine den Rillen in der Vertiefung der Tragplatte entsprechende Rippenstruktur auf, so daß nach dem Zurücksetzen des Gebißmodells oder der Kiefer- und Zahnsegmente auf die Tragplatte die Rippen an den Außenwänden des Gebißmodells oder der Segmente in die Rillen der Seitenwände der Vertiefung der Tragplatte eingreifen.After curing in the negative impression of a patient's denture filled liquid model mass, e.g. Plaster on which the support plate of the well-known Design was placed before curing, this shows from the deepening of the Carrier plate raised positive dentition model on the outer walls and the grooves in the recess of the support plate corresponding rib structure, so that after the Resetting the denture model or the jaw and tooth segments on the support plate the ribs on the outer walls of the denture model or the segments in the Engage grooves in the side walls of the recess in the support plate.
Das hat jedoch den Nachteil, daß es sowohl beim Ablösen des Gebißmodells von der Tragplatte, als auch beim Zurücksetzen und wiederholten Herausnehmen des Gebißmodells oder einzelner Gebißmodellsegmente zu einem starken Abrieb an den Kanten des Gebißmodells bzw. seiner Gebißmodellsegmente kommt.However, this has the disadvantage that it is both when detaching the dentition model from the support plate, as well as when resetting and repeatedly removing the Denture model or individual denture model segments to a strong abrasion on the Edges of the bit model or its bit model segments comes.
Auch beim Zurücksetzen und Einfügen eines Gebißmodellsegments an eine falsche Stelle im Gebißmodell in der Vertiefung der Tragplatte entsteht Abrieb oder Bruch an den Kanten des - meist aus Gips hergestellten - Gebißmodells. Also when resetting and inserting a bit model segment to an incorrect one A place in the denture model in the recess of the support plate creates abrasion or breakage on the edges of the denture model - usually made of plaster.
Bereits durch kleinste Schäden am Gebißmodell bzw. Kiefer- oder Zahnsegment, etwa durch Splitterkanten oder Abrieb der Modellmasse, ist jedoch ein paßgenauer Sitz des Gebißmodells bzw. -segments auf der Tragplatte nicht mehr gewährleistet, so daß der nach dem Gebißmodell angefertigte Zahnersatz später im Mund des Patienten schlecht sitzt.Even the slightest damage to the bit model or jaw or tooth segment, through splinter edges or abrasion of the model mass, however, is a more precise fit Fit of the bit model or segment on the support plate is no longer guaranteed, so that the dentures made after the denture model later in the mouth of the Patient sits poorly.
Der Erfindung liegt die Aufgabe zugrunde, eine Tragplatte für ein Gebißmodell zu schaffen, die das wiederholte Abnehmen des Gebißmodells oder einzelner Kiefer- oder Zahnsegmente von der Tragplatte und das paßgenaue Zurücksetzen des Gebißmodells oder einzelner Gebißmodellsegmente auf die Tragplatte ohne Abrieb der Modellmasse ermöglicht.The invention has for its object to a support plate for a denture model create the repeated removal of the denture model or individual jaw or toothed segments from the support plate and the precise reset of the Denture model or individual denture model segments on the support plate without abrasion the model mass enables.
Erreicht wird dies durch eine Tragplatte für ein Gebißmodell, bei welcher die äußere Seitenwand der bogenförmigen Vertiefung auf der Tragplatte etwa um ca. 4/5 in ihrer Höhe verringert wird im Vergleich zur inneren Seitenwand.This is achieved by a support plate for a bit model, in which the outer side wall of the arcuate depression on the support plate is reduced by approximately 4/5 in height compared to the inner side wall.
Vorteilhafterweise weist die innere Seitenwand der bogenförmigen Vertiefung auf der Tragplatte eine Stufe in der Höhe der gegenüberliegenden verbliebenen äußeren Seitenwand der bogenförmigen Vertiefung auf, ist die Wand der Stufe senkrecht oder schräg ausgebildet und sind die senkrechte oder schräge Wand der Stufe der inneren Seitenwand sowie die äußere Seitenwand der bogenförmigen Vertiefung auf der Tragplatte jeweils zur Hälfte unterschiedlich konturiert, wobei unterschiedlich konturierte Seitenwände einander gegenüberliegen.The inner side wall of the arcuate depression advantageously has the support plate one step at the level of the opposite remaining outer Sidewall of the arcuate depression, the wall of the step is vertical or formed obliquely and are the vertical or sloping wall of the step of inner side wall and the outer side wall of the arcuate depression the support plate each contoured half differently, with different contoured side walls lie opposite each other.
Zweckmäßigerweise sind die senkrechten Rillen der verbleibenden inneren Seitenwand oberhalb der Stufe sich nach unten verjüngend ausgebildet.The vertical grooves are expediently the remaining inner ones Sidewall above the step tapering downwards.
Bei einer weiteren Ausführungsform der Erfindung sind die sich zwischen den senkrechten sich nach unten verjüngenden Rillen befindenden Rippen nach unten hin sich verbreiternd ausgebildet.In a further embodiment of the invention, the are between the vertical ribs tapering downwards towards widening.
Bei einer anderen Ausführungsform der Erfindung weisen die in den Bohrungen steckenden Haltestifte an ihren in die bogenförmige Vertiefung auf der Tragplatte hineinragenden oberen Enden ein Gewinde auf.In another embodiment of the invention, the have in the bores sticking pins on their in the arcuate recess on the support plate protruding upper ends a thread.
Zweckmäßigerweise weisen die Haltestifte an ihren auf der Unterseite der Tragplatte herausragenden Enden einen Schlitz auf. The holding pins expediently have their on the underside of the Support plate protruding ends a slot.
Nachfolgend wird anhand der Zeichnungen eine Ausführungsform der Erfindung näher erläutert und beschrieben.An embodiment of the invention is described below with reference to the drawings explained and described in more detail.
